Ventless gas heaters are devices used for heating a room without exchanging outside air. Typically, these heaters do not have a vent and they do not draw air from outside. In fact, they work on the oxygen that is available in the room. The combustion process of generating heat is fueled by oxygen that is present in the room. Some variants of these gas heaters work on either LPG (liquefied petroleum gas) or natural gas.
There are different types of ventless heaters like blue flame, radiant heater, gas log version and space heaters. Each of them has a different system of heating and combustion. They use either of the two types of fuel and derive oxygen from inside the room for the process of combustion. These heaters have been preferred over the traditional ones for many reasons. Here are some of the advantages of propane ventless heaters.
Installation: Ventless gas heaters do not require a flue, chimney or external venting ducts. The installation charges are almost zero as compared to the traditional gas or wood fireplaces. Moreover, some units can simply be mounted on the wall and all you need is a nail to be affixed on the wall. Some of these heaters can stand on their own and do not require any kind of installation. This helps in saving additional cost of installation.
Cost Effective: These heating systems offer the highest fuel efficiency, which is up to 99.9 percent. This means that the gas is completely used without any wastage. Unlike a natural gas space heater, the other types of heaters produce harmful emissions. However, gas and propane heaters burn all the fuel consistently and do not produce any emissions like smoke, carbon monoxide and so on. They perform much better than the traditional heaters and help you save money. The fuel efficiency ensures that you do not require frequent refills.
Environment-Friendly: Ventless gas heaters use natural gas and LPG that are clean fuels and are known to be environment- friendly. They do not produce harmful emissions like carbon monoxide and are not a threat to human beings. This heating system can be used as an alternate source of heat.
Apart from the above-mentioned advantages, the natural gas garage heaters have many other benefits. These too, like the room heaters, offer high efficiency. You can expect high fuel efficiency and clean heating solutions. This heater is quiet since it has no large air mover and there is no noise pollution either. Moreover, these heaters are portable, so you can move them around in your garage or take them along for your outings.
There are different variants available and infrared garage heater is another option available. This heater also works on propane or natural gas. However, it uses the infrared technology, which is akin to the sun’s warmth. Such ventless gas heaters heat the surface.
The gas fueled infrared heater is mounted overhead and it directs infrared energy on the floor, which is a surface. This energy or heat is absorbed by the floor and all the objects become warm. In fact, the warmth is spread in the air too. A thermostat is used to shut off the infrared heater when the desired warmth is reached.
